AEM Series 2 SR20det

Good day. I was wondering if an AEM series2 that is “configured” for 2jz can be reconfigured for SR? I’m currently looking to add some injectors, Q45 MAF and bigger turbo to my car. Of course I could send in the factory ECU to get programmed for that but what fun would that be? Plus the easy route would not be fitting for this Forum. I have Greddy Blue piggyback ecu with SR harness and figured I’d go that route too to get my feet wet but wanted to ask about the AEM s2 seeing someone is selling it at a discount. The Greddy Blue can be configured for multiple ecu and manufacturers but I don’t see any paperwork that shows the AEM can be configured by manual settings on it as well.
